We performed an analysis similar to that described in 42880. The bumps around Mains harmonics (the bumps are especially large at odd harmonics: 150Hz, 250Hz,  350Hz, 450Hz  but are present also around even harmonics: 200Hz, 300Hz, 400Hz) are correlated in blind way with the low frequency component (<10Hz) of several signals (including ASC*, SBE_*LC*, Sc_*, LSC_B*_DC, SDB2_B*_PD*_56MHz*) . The channel list and the results are posted below.

We find signals ASC_DIFFp_TY and SDB2_B1s1_PD1_56MHz_I   seem to explain well most of sidebands.
